Hunt Institute Archives Text Discovery Platform

Search a large and growing portion of our online collections, including handwritten documents.
PROTOTYPE

This prototype uses state-of-the-art artificial intelligence, including a vision-language model (VLM) capable of reading handwritten documents as well as typed and printed text, to create searchable transcriptions of digitized materials in the Hunt Institute Archives. This makes it possible to search the textual contents of individual pages, including material that may not be described in the archival catalog.

Use Keyword search for specific words, names, dates, scientific names, or phrases. Try Semantic search (experimental) to describe a topic, question, or kind of material when you do not know the exact wording used in the documents.

About the AI-generated transcriptions

The transcriptions are generated automatically from page images and may contain errors, especially with difficult handwriting, unusual names, multiple languages, image-quality problems, or complex layouts. They are intended primarily as a discovery aid rather than authoritative transcriptions.

Each result provides the generated transcription and links to the original digitized material and associated archival description so that readings can be checked against the source. The transcription workflow uses AI models run locally by the Hunt Institute.

About Keyword and Semantic search

Keyword search is the default and matches the wording in the transcriptions. Results contain all your terms. Use quotes for an exact phrase. Substring matching is supported, so aceae can find plant-family names ending in -aceae.

Semantic search (experimental) is useful when you know what kind of material you are looking for but do not know the words used in the documents. It ranks transcribed passages by similarity of meaning, so relevant results may not contain the exact words in your query.

Semantic queries can be broad research topics, descriptions of activities or relationships, or natural-language questions. For example:

plant collecting and fieldwork in South America medicinal, culinary, or other traditional uses of plants chromosomes and plant classification early herbals and botanical illustrations botanical institutions exchanging plants, seeds, and specimens microscopy and photomicrography in botanical research How did botanists and gardeners introduce plants from one region to another? grafting, budding, and propagation of tropical fruit crops

Semantic search is not a chatbot: a question is used as a search query, and the system returns archival passages that appear conceptually related to it rather than generating an answer or summary. Short descriptions and ordinary research questions generally work better than lists of disconnected keywords. Quotation marks have no special meaning in Semantic mode. Cross-language matching may work in some cases, but it should not be treated as translation.

Keyword and Semantic search are complementary. Keyword search lets you require particular wording; Semantic search can surface differently worded passages about the same subject. Depending on the research question, trying both can reveal different useful material.

Open a result: use the prominent page-and-transcription link to see the metadata, PDF, and full transcription. Keyword-search terms are highlighted in the transcription.

Archives Collections Database (ArchivesSpace): the Collection, Item/Folder, and Digital Object links open the corresponding archival records. Collection-level dates describe the collection as a whole, not necessarily the specific item or page.

If a PDF does not load: on the detail page, use the Digital Object link, click “Go to file” in ArchivesSpace, and navigate to the page number shown here.

Current limitations
  • Automated transcriptions can contain missing or incorrect text or unintended repetition. Difficult handwriting, image quality, unusual layouts, and multiple languages can reduce accuracy. Always consult the original page image when an exact reading matters.
  • Semantic search remains experimental. Its rankings are an additional discovery aid, not a complete or definitive set of relevant results, and highly ranked pages can sometimes be only broadly related.
  • This is an active prototype. Search coverage, transcriptions, functionality, and the interface may continue to change as additional archival material is processed and the system is improved.

Mr. Walter S. Heller
Mills Tower
San Francisco, California

Dear Mr. Heller:

Thank you for your letter of the 21st and the opportunity to see the fine kodachromes you enclosed and which I am returning herewith. You certainly kept the palms in the Rio Botanical Garden a lot straighter than I was able to keep them! I have never had more than a few hours at a time in that remarkable Garden and hope some day to be able to study it in detail. I am sorry that offhand I cannot identify the flowering shrub you photographed but should be able to get a determination from some of my Brazilian colleagues.

The views of the "Switzerland of South America" are very nostalgic and tantalizing. There is no area in either America which is more promising and important botanically than southern Chile from Concepcion to Chiloe, especially on the coast but also in the Cordillera. The vegetation of much of this area is practically unknown and the relatively short periods over the past 17 years during which we have been able to collect there have yielded much valuable information on plant distribution and a number of new species. As a potential source of new or little known ornamentals, especially perennials, for the Bay Region and farther north it is unique. I hope that it may be possible, sometime in the future, to finance a plant hunting expedition which will be able to operate exclusively in that area.

Would you or any of your friends care to grow some of the attractive south Chilean ornamentals? I am thinking particularly of Lapageria rosea, El Copihue, the Chilean national flower, an attractive red-flowered climber that does well in Berkeley on oaks and redwoods. In this Botanical Garden we have a number of surplus plants in gallon cans which should flower in a year or two. I am enclosing a poor indication of what the flower can be.

With best wishes

Cordially,

THG:T
